One more time, for clarity. If these people had truly observed AND RECORDED, in some way, the previous position of a sunset and are now observing a change, which they are also documenting, then they might have something. As it is, they are thinking back, in retrospect, and saying that they REMEMBER the sun being in a different place. See the difference?
